Sometimes I want to download recursively from an FTP server and I don’t want to leave the command line. Depending on your FTP client, you may be lucky enough to have an option built-in for this but in many cases you don’t. FTP clients often feature mget, which is good for downloading files based on a glob filter such as *.txt or *.c. But still, this isn’t recursive.
Surprise! Wget supports FTP and can download recursively! You could download the full contents of an FTP server like this:
wget -r 'ftp://user:pass@host'
Or just grab a single directory like this:
wget -r 'ftp://user:pass@host/dir'
